    PERFECT FIT!

    These are my first leakproof so I decided to buy four pairs. I love the material and the wide waist band and as a bonus they are so comfortable to wear.

    Love the band and the material

    I bought the grey pair because I loved the colour and the band but didn't want the boxer style. I was hesitant because I do prefer a brief style since I am a larger shaped body. French cut is not my thing. I was right I'm not a fan of the cut but WOULD LOVE this material and waist in a brief style. I will wear these ones obviously but would buy 20 pairs of they were in a brief cut. Perfect absorbance and placement for me. I just need more of my tummy covered.

    Very comfortable

    I like these underwear (I have a large/round butt) so a lot of underwear slide inwards, but these have enough coverage to stay put. I would say it is a "generous" cut. I wear a small size.

    These are on sale for a reason

    These look great and they seem like a great choice on first try, but I had issues with both colors: the black had the elastic separate from the body forming a hole on the 2nd wash (after the first wear; washed before wearing of course). The grey/taupe is pilling like crazy on the elastic; it's like the elastic is disintegrating. I'm glad I have other pairs to fall back on, but this was a total waste buying multiple pairs of these modal rib, which is unfortunate as they're so soft and comfortable.
